问题
When I published my app to shinyapps.io, I came across the following issues:
- PhantomJS
- file(con, "rb"): cannot open the connection
The full log in the output pdf file:
PhantomJS not found. You can install it with webshot::install phantomjs(). If it is installed, please make sure the phantomjs executable can be found via the PATH variable.
Warning in normalizePath(f2): path[1]="./webshot6c3d201217.pdf": No such file or directory
Warning in file(con, "rb"): cannot open file ’./webshot6c3d201217.pdf’: No such file or directory
Error in file(con, "rb"): cannot open the connection
A tibble: 0 x 2

I can create the PDF successfully after installing PhantomJS on my local Shiny server, however, I have no idea how to address it on shinyapps.io.
